BOAT.

Specification of Letters Patent.

Patented nly 19, 1910..

Application filed September 28, 1909. -Seria1l lo. 520,047.

To all whom it may concern:

Be it known that I, Anpnnw Eon, citizen of the United States otllnierica, residing at the city of Duluthyin the county-of St. Louis and State of Minnesota, have invented certain new and usefulImprovements in Boats, of which the following is a specification.

My invention relates to improvements on boats.

It consists of three parts: first, a plane with upward curve in the front end; second, a now arrangement of propeller, which in conjunction with the plane carries the boat, when in motion, on the sur ace of the water; third, :1. safety sheet to protect it against wind and waves.

The object of this invention is threefold; first to greatly increase the speed; second, to reduce the operating expenses; third, to add to the comfort and safety of passe 'gers.

I attain these objects by the construction illustrated'in the accompanying drawin Figure 1 is a. vertical side view of the boat. F lg. 2 is an outside view of the bottom.

Same letters refer to same parts in both views.

a. is a smooth plane secured to the boat. The upward curved end will rise and lift the how. The straight part, being of saith clout size, will when in. full speed car y the entire boat on the water surface.

I) is a bracket in which the propeller shaft turns and secures shaft in the stern end to the plane and boat. The rudder f also at tached to this bracket. The bow end of the propeller shaft 0 passes through the heat shaped body at and is there connected with the machinery c is an extended spindle shaped propeller hoss which carries two or more propeller 'hlmlcs. 'lhcsc blades alternate along and around the boss equally spaced alnl in equal angles to each other. This hoss cuts through the water like a. fish while the ordinary boss acts in the water like a hall in motion would, meeting resistance and disturbing the water in proportion to rate of speed. it is plain this extended spin-:llo shaped hoss will overcome lUllSllltlillllU resistance, and with the blades in position as herein ilcscrihcil it is less inclined lo churn the water \ililll the ordinary propeller, and consequently posgreater propelling capacity. Another important gain with this arrangement of propeller is it propels in two directions, forward and upward in proportion to the angle of shaft to the Water plane. The boat must be made so that it lies deeper in the water at the how when not in motion. This gives the plane an upward slant toward the stern and makes it possible to move stern-ward.

g is asafety sheet, one on each side. Run.- ning parallel with the plane and being smooth and thin as strength will allow it will not make much resistance but render the overturnin of the boat an impossibility.

h is a brac ct holding the safety-sheet firm to the plane.

Because the plane and arrangement of propeller, as illustrated and specified, carries the boat on the surface of the water and relieves it from the wave-making resistance, which is the principal hind 'ance to high speed and which also causes so much waste of power, it will be possible to increase. the speed to double that obtained by boats hitherto. Higher speed is gained without increase of power, therefore it naturally do creases the operating expenses. The plane protects the boat from the play of the waves and so adds to the comfort of passengers. The safety sheets render it impossible for the laigest waves and the strongest. winds to overturn the boat, thus making life safer on Water.

I claim:

A boat body, a plate surrounding the boat and attached thereto at the lower portion of the boat and having an upwardly curved.

forward end, safety sheets attached beneath the plate near the forward portion of the boat, and a propeller slnfit with the specified l'orln ol propeller it carries and extending rcarwartlly and downwardly under the boat holly. suhslantially as described.

l n testimony whereof I affix my signature in presence of two witnesses.
